IMPROVEMENT IN WATER-CIRCULATING PIPES FOR STEAM-BOILERS.

Specification forming part of Letters Patent No. 127,466, dated June 4, 1872.

T 0 all whom it may concern:

Be it known that I, WILLIAM DILLON, of the city of Wheeling, in the county of Ohio and State of West Virginia, have made the inside of the mud-arrester, as hereinafter described. The object of my invention is to af ford an opportunity to enter and clean out the mud-arrester while the boiler is in operation.

Figure 1 is a front elevation of boilers. Fig. 2 is a side elevation of same. Fig. 3 is a plan or top view. Fig. 4 is an end elevation.

A A, two steam -boi1ers; B B, two fireboxes; 0 C, water-circulatin g pipes, intersect-- ing mud-drum D, (of ordinary construction,) and leading therefrom to the front of the boiler, and entering therein near its bottom, the object of which pipe will be hereinafter more fully shown. E, mud or sand arrester, provided with discharge-cock); the object of which arrest-er is to arrest the mud and sand in the water and separate them therefrom, as the water passes through it, by means of any suitable open material placed therein. 9 g, valves in pipes C C, to stop the flow of water through them, so that the discharge cock f can be opened to let out the mud deposits inthe arrester, or so that one of the cooks can be closed and the other partly so, so that the mud deposits can be blown outof the arrester through the cock f. The arrester E can also be taken off and cleaned out.

General Operation.

In the heating of the boiler the bottom of the front part, immediately over the fire, be comes and remains the hottest, which causes the water therein to circulate or flow from the rear to the front through the pipe 0, and thence back again to the rear through the boiler, and

so on in a continuous current, which prevents,

in a great measure, the conflict of currents which takes place in a boiler when the water flows backward and forward within the same. The water, by its repeated passing through the mud-drum and mud-arrester, becomes divested of the most of the mud or sand therein, which, together with the back direct current of the water through the boiler greatly prevents tne formations of inc-rustations upon the boiler.

From the above-described movements of the water and its great, if not entire, separation from extraneous matter, follow theresults hereinbefore mentioned, namely, a more uniform temperature of the water throughout the boiler; economy in steam and fuel; durability of boilers; and an increased protection against explosions.

IVhat I claim as my invention, and desire to secure by Letters Patent, is-

In combination, the water-circulating pipe 0, mud-arrester E, and cocks g g, substantially as and for the purpose set forth.

WILLIAM DILLON.
